Glossary

Cisco IOS Release: Multiple releases (see the Feature History Table)

of Management Information (SMI), protocol operations, management architecture, and security.

SNMPv3 provides secure access to devices by a combination of authenticating and encrypting packets

over the network.

SSH—Secure Shell Protocol. A protocol that provides a secure remote connection to a router through a

Transmission Control Protocol (TCP) application.

UDP—User Datagram Protocol. Connectionless transport layer protocol in the TCP/IP protocol stack.

UDP is a simple protocol that exchanges datagrams without acknowledgments or guaranteed delivery,

requiring that error processing and retransmission be handled by other protocols. UDP is defined in

RFC 768.

VoIP—Voice over IP. The capability to carry normal telephony-style voice over an IP-based Internet

with POTS-like functionality, reliability, and voice quality. VoIP enables a router to carry voice traffic

(for example, telephone calls and faxes) over an IP network. In VoIP, the digital signal processor (DSP)

segments the voice signal into frames, which then are coupled in groups of two and stored in voice

packets. These voice packets are transported using IP in compliance with ITU-T specification H.323.
